SQ6601PT

Semiconductor SQ6601PT Off-Line Quasi-Resonance Flyback Switching Regulator Description The SQ6601PT is a hybrid IC consists from power MOSFET and a controller IC, designed for Indirect feed-back Quasi-Resonant (including low frequency PRC)fly-back converter type SMPS (Switching Mode Power Supply) applications. this IC realizes high efficiency, low noise, downsizing and standardizing of a power supply system reducing external components count and simplifying the circuit designs. the device is provided in a five pin overmolded TO-220 style package, affording dielectric isolation without compromising thermal characteristics. (Note). PRC is abbreviation of “Pulse Ratio Control” (On-width control with fixed OFF-time). Features Quasi-Resonant Operation Low-loss, Pulse-Ration-Control standby mode Under-voltage lockout with Hysteresis Adjustable switching speed for EMI control Low start-up circuit current (100uA max) Active low-pass filter for stabilizing the operation in case of light load Avalanche Energy Guaranteed MOSFET with high VDSS Built-in constant voltage drive circuit Built-in step drive circuit Built-in low frequency PRC mode (≒20kHz) Pulse-by-pulse Overcurrent Protection (OCP) Overvoltage Protection with latch mode (OVP) Thermal Shutdown with latch mode (TSD) Over-molded Five-Pin Package www.DataSheet4U.com Ordering Information Type NO.
